Objective To determine the influence of total glucosides of paeony (TGP) on bone density, protein level of skeletal muscle and relative cytokine of osteoporotic rats. Methods Six-month-old SD rats were shamed as control (8 rats) or were ovariectomized (24 rats). The ovariectomized (16 rats) +TGP low dose and high dose group were treated with 50 mg/(kg?d) TGP and 150 mg/(kg?d) TGP respectively for 12 weeks. After the animals were sacrificed, IL-6, TNF-?, IGF-1, TGF-? in serum, protein level of skeletal muscle in right quadriceps femoris, and bone density of right femur and lumbar vertebra were determined. Results Compared with the ovariectomized group, the bone density and the protein level of skeletal muscle in TGP group increased significantly from the baseline (P

Objective To research the relationship between the serum level of cystatin C (CysC),N-terminal pro brain natriuretic peptide (NT-proBNP) and the cardiovascular (CV) events in maintenance hemodialysis (MHD) patients,looking for a new and effective biological prediction method for cardiovascular disease (CVD).Methods According to the excluded criteria and included criteria,a total of 126 patients [male 67(53.2％),female 59 (46.8％)] were included in this study,screening out of 452 MHD patients from 3 blood purification centre,no secondary hyperparathyroidism,blood pressure controlled,hemoglobin standard,no lipid abnormalities,and without history of coronary heart disease,heart failure and arrhythmia.Participants adopted 3 dialysis treatment,including hemodialysis,hemoperfusion and hemodiafiltration.Every 3 months before the dialysis,the Cys-C,NT-proBNP,serum phosphorus,serum intact parathyroid hormone (iPTH),hemoglobin and electrocardiogram were detected.The heartbeat ultrasound was examined every 6 months,observed for 24 months and followed up for 3 years,recording the incidence and the inspection results.The correlation and the occurrence of CVD were analyzed by conducting a multiple factor logistic regression analysis.The forecast performance of Cys-C,NT-proBNP was evaluated by using receiver operating characteristic (ROC) curves and area under curves (AUC).Results Eighteen episodes of CV events occurred in 126 patients during the experiment and follow-up,including 8 episodes of heart failure,4 episodes of myocardial infarction,6 episodes of arrhythmia.Detection indexes had no statistically significant correlation (P ＞ 0.05),and the results of ECG and ultrasound heartbeat graph showed that no significant difference in cardiac structure and function before treatment (P ＞ 0.05).After 24 months duration,the research showed that the level of serum calcemia was lower,and the levels of phosphorus and iPTH were higher in hemodialysis group compared with that in the other 2 groups,and the differences had statistical significance (P ＜ 0.05).The median levels of Cys-C and NT-proBNP were 8.59 (9.74,7.10) mg/L and 7 739 (9 887,6 736) ng/L in the patients CV events occurred.Non conditional multivariate logistic regression analysis demonstrated that the increasing interdialytic weight,Cys-C,NT-proBNP,iPTH,dialysis hypotension were the independent risk factors of CV occurrence.AUCs to predict CVD occurrence in MHD patients was 0.64 (95％CI 0.53-0.71,P ＜ 0.05) and 0.79 (95％CI 0.72-0.89,P＜ 0.01) using Cys-C and NT-proBNP respectively.The cut-off values of serum Cys-C and NT-proBNP for CVD occurrence were 8.59 mg/L and 7 739 ng/L,with a sensitivity of 84.3％ and a specificity of 92.7％.Conclusions Cys-C,NT-proBNP can be used to predict the risk of CV events in dialysis patients.

This paper reports 17 cases of hypomagnesemic convulsiens of the newhorn that were admitted from Se-Ptember 1981 to January 1983. Only 2 patients were breast-fed.Symptoms and signs of hypomagnesemia are indistinguishable from these of hypocalcemia unless the serum magne-sium is determ ined. Serum magnes iumlevels had been determined in 50 normal children. The average value-2 standard deviation=2.17-2?0.34=1.49mEq/L.We defined hypomagnesemia as the serum magnesium lcvels below 1.48mEg/L. The serum magnesium levels of 17 patients varied from 0.65 to 1.46m Eq/L. Of 10 cases serum calcium le-vel6mg/dl.2.5%MgSO_4 was given intraveno-usly by continuous infusion in a dose of 2-4ml/kg every 12 hours. After the convulsions had been controlled a dose of 25% MgSO_4 was given intramuscul-arly in a dose of 0.4ml/kg twice daily Convulsions usually ceased after 1--4doses of MgSO_4, but the serum magne-sium levels did not rise to normal le-vels until 2-6 days. The convulsions could not be controlled by repeated ad-ministrations of calcium gluconate in 5 patients who had both hypomagnes-emja and hypocalcemia. Only after theadministiation of MgSO_4 did the serum calicum levels rise to the normal level and the convulsions cease.Electrocardjograms recorded in 7 patients all were abnormal but 1 case,so we should pay attention to the inf-luence of magnesium upon the heart.

AIM:To explore the inhibitive effects of cervical lymphadenectomy on kerstoplasy after alkaline burns.METHODS:The Wistar rats' corneas were transplanted into Sprague-Dawley(SD)rats' eyes which were randomly divided into 4 groups:group A(control group);group B,the cervicallymphadenectomy group;group C,corneal transplantation after the alkali burn injury;group D,cervical lymphadenectomy following group C.Out of 6 rats in each group,the cornea of one rat Was used for mawophage immunohistochemistry at day 14 after the transplantstion,and the remaining 5 rats were used for studying corneal immune rejection with a slit lamp.The time when allograft rejection occurred was recorded and mean survival times(MST)were compared among the groups.RESULTS:Compared with the MST of group A(10.40±1.14 days),the MST of group B(46.30±9.46 days)Was significantly longer(P＜0.05).MST of grafts between group C(7.00± 1.58 days)and group D(15.00±3.39 days)was also significant (P＜0.05).At 14th day after the transplantation,there was no CD68 immunoreactivity in the graft of group B,and CD68 proteins were expressed to some extent in the grafts of group A and D.However,in the graft of group C,the expression of proteins Was dramatically up-regulated.CONCLUSION:Cervical lymphadenectomy therapy has a significant effect in preventing corneal allograft rejection in normal and alkali burned oorneai beds.

Compounds 3 and 5 showed potential antioxidant activities with malondialdehyde inhibitory rates of 53.2% and 56.1%, respectively.

Objective To review the clinical features and the follow-up results of 317 cases of patients treated with artificial heart valve replacement and evaluate the curative effect.Methods Data of 317 patients underwent artificial heart valve replacement from July 2005 to June 2010 was analyzed,among them,284 patients replaced with mechanical valve and 33 patients with biological valve.Clinical features including age,etiology,surgical approach,valve type,etc,were summarized and the recovery of cardiac function,the incidence of complication and mortality were observed through postoperative follow-up.Results There were 6 patients died in the perioperative period and 311 survived.Two hundred and ninety-one cases were followed up and the follow-up rate was 93.57％.The time of follow-up is 1.00 to 4.75 years( with average:2.23 ±1.37 years).The cardiac function(NYHA) was significantly improved after operation ( grade:2.05 ± 0.29 vs 3.17 ± 0.62 ) ( t =2.366,P ＜ 0.05 ).It was related to age,cardiac function before operation ( P ＜ 0.05 ).One patient died during the follow-up period.The statistics analysis showed that the long-term incidence of complication was related to the type of heart valve prosthesis ( P ＜ 0.05 ).Conclusion The therapeutic effect of artificial heart valve replacement surgery appears satisfactory.Heart function is improved significantly and the survival rate is high.Reasonable timing of surgery,appropriate type of prosthetic valve and intensified clinical follow-up can help to reduce the occurrence of postoperative complication.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.
